Hello everyone, I almost got all the parts to this problem: In an RC series circuit, = 11.0 V, R = 1.10 M, and C = 1.80 µF. (a) Calculate the time constant. 1.98 s (b) Find the maximum charge that will appear on the capacitor during charging. 19.8 µC (c) How long does it take for the charge to build up to 9.0 µC? s I tried the following: q(t) = Q[1-e^(-t/RC)] q(t) = 9.0e-6[1-e^(-1.98)] = 7.75e-6s, which is wrong; Since i know t = RC, and i found RC = 1.98, would it be q(t) = 9.0e-6[1-e^(-1)] ? I just tried this and its also wrong.
